The System Architecture of Smart Water Grid for Water Security

Architecture of smart water grid based on Internet of Things was proposed, mainly including hierarchy framework, technical system and function framework. The hierarchy framework is consists of real-time active sensing layer, interconnecting layer of water information interconnection layer, and smart decision layer. The technical system mainly contains the techniques,e.g.,the multi-carrier network composing and real-time transporting, intelligent storage of mass data and the seamless docking of multi-modules of the system, the coupled simulation of multi-dimensional water model, the evaluation and diagnosis of water security risk,the fast and dynamic forecasting model building of water pollution incidents, the multi-objective optimization and control technology of water quality and quantity of cascade reservoirs, the dynamic early warning technology in the unexpected water pollution incidents, the emergency disposal technology of the multi-scale, multi-type and multi-objective unexpected water pollution incidents. The functions framework includes the modules, e.g., intelligent sensing, intelligent simulation, intelligent diagnosis, intelligent early warning, and intelligent regulation, intelligent disposal, and intelligent control, et.al.
